BAG-TYING MACHINE.

Specification of Letters Patent.

Patented Jan. 13, 1914.

Application filed May 26. 1910. Serial No. 568,562.

2" 1 all whom it may concern:

o it known that I, HERMANN A. KLEMM, a itizen of the United States, lQSldlIlg in Harrison, county of VVestchester, State of New York, have invented certain new and metal Improvements in Bag-Tying Macf ines, of which the following is a specification.

This invention has reference to bag tying machines of the kind described in my application for Letters Patent No. 556,375, filed April 19, 1910, and relates particularly to the improvements in the knotting device and its allied mechanisms.

It contemplates the use of a hooked latch needle for engaging the leading end of the tying twine and passing it inside of the loops of twine wrapped around the neck of a bag or between said loops and the neck of the. bag.

It also includes modifications and other novel features in the construction and ar rangement of some of the operative parts of the machines, as shown in the accompanying drawings and hereafter fully described.

Figure 1 a plan view of the machine embodying the present improvements, with the upper part removed. Fig 2 is a righthand side elevation with the vertical shaft and twine carrier in section. Fig. 3 is a plan view of the upper gears shown in Fig. 2, taken on the line 3, 3 Fig. 2. Fig. t is a modification in the twine holding rccl. Fig. 5 is a side view of the latch needle constituting the knotting device, detached. Fig. 1 shows, in plan, the primary crushing or creasing device. Fig. 7 is a front elevation of all of the creasing devices and bag ncck holding devices. Fig. 8 is a side elevation of the parts shown in Fig. 7. Fig. 0 a horizontal section of the bag mouth h lding jaws taken on the line 0, 0, Fig, Fig. 10 is a vertical section of the same. on the line 10, 10, Fig. 9. Fig. 11 is a horizontal scetion of the upper preliminary ncck crcascrs, taken on the line 11. 11, Fig. T. Fig. 12 is a plan of the latch nccdl its operating mechanism and twine controlling dcvicc, on an enlarged stillc. Fig. 13 is a side clcva tion of the same. Figs. 11, 'l. 1t? and 17 illustate various stagcs in the [Wot-Ms of securing the knot by a hooked latch needle. showing a side view of thc ncck of a bag. and Fig S. 18, 19, l0 and 21 arc rcar views of Figs. 14, 15, 1G and 17 respectively.

The machine in its general features of construction and the operating devices actmg on a bag to crease the neck and close the mouth and actuate the other parts of the machine is similar in all essentials to the machine of my before mentioned application and corresponding parts are in the drawings of this case similarly indicated, and it will only be necessary to briefly describe the same to-imparta proper understanding of the novel features of this invention, the driving gear, &c., being here omitted.

The preliminary neck creasing and gath ering jaws 02, (33are closed onto the lower part of the. neck of the bag as it passes between them into tying position; the jaw 62 is carried by the sliding rods 64, and has an opening through it in line with a slot formed in the bed of the machine for the passage of the new form of knotting needle 111. and its carryin lever hereafter described, and at the end 0 "this slot is placed a thin guard plate 112 to prevent the neck of the bag entering the slot and to hold it away from the needle. The other jaw 03 rocks on the vertically arranged pivot (5-3 and the neck pusher ()7 is rocked on the stud 68 by the operating lever 87 pivoted at 88 and connected to an arm of the pusher (17 by a link 80. The other preliminary neck creascrs which act on the upper part of the neck to close the mouth of the bag are carried on the ends of the curved arms l00 pivoted at 101 to the standard 1/. said arms being by the short links 102 operated and controlled by the lever 10?) having a pivotal connection 104 on the standard and having a universal connection 105 at its other end with the upper end of the opcrating rod 100. The ClOsing jaws 113 of this preliminary ereaser are angularly formed and secured to the lower ends of the arms 100. as shown at Fig. 11, and their ends or edges 114 interlock. This construction of the jaws insures a perfect action on the mouth of a bag. whether made of a fabric or paper. to properly crease and close the same ready for the action thereon of the device for holding the mouth closed while the tying twine is being applied to the neck. The jaws 115 of the bag mouth holdcr are similar in construction to the jaws 1t? and have interlocking flaring cdgcs 110; they are carried by arms 2 pivotcd at 3 to a collar on the lower end Of the vertical hollow shaft 7 and by the links 4 are connected to the arms 5 of a sleeve 6 fitted to slide on the. shaft 3 and controlled by a lover 7, pivoted at 8 to n hraeket from the stamlnrd and actuatwl by a mm 0 on the in (1 held in bearings, f1, ll, of the 11121:" n10. inner face of one of tho jaws 115 l p z with n czno shiipl'n'i piano l 1i" who-- l"; is to deprass the neck oi ill? linoliling needle ill .95 (inc ja tho nwli to insure the? prop-'21" 11 'll live lwizuin winiilm in i311 pl'tav'fllh inl'uliemnws of (he n i in at; Fig ll";

Tho grip ping jaws l! and ll" which holil the luilling end of the twine are shown in Fig. 18 as are also shown the twine guide pin 56 and the twine cutter 47, These views represent the first silage oi securing the mouth of a bag by t'wino. The. second stage is illustrated in Figs 15 and 19; hvre tho noodle has lHOVQd up to bring its latch 130 shove the loops of twine, and the grippers l7 and 19 hhvv also lJPAH lifted. to sol. the lhalling enil ol' 1 h? twine in pomzilhn lo Cl'llEl" lho hooked porlion of the mwlla', {he twin:- heing properly llllil l5 held on the end of the lever 18 by means of a notch formed in its upper edge, and to cause the twine to be pressed against the needle to insure its engagement by the hook at pusher 132 is provided, which is controlled and moved horizontally as hereafter described. The guide pin 56 has also been raised at about this time to hold the feeding end of the twine. in position to be severed by the cutter 47 when it moves forward. In the. next stage or step in the tying process, shown in Figs. 16 and 20, the needle has moved down a sutlicient distance for its latch 130 to be raised, by contacting with the top loop of the twine. and to close the mouth of the hook holding the leading end of the. twine, the pusher has partly moved back and the grippers 17 and 19 have commenced their downward movement and are about to release the leading end of the twine. The tying is completed as shown in Figs. 17 and 21, the grippers having opened and dropped into their lowermost position, the needle moved down so as to draw the leading end of the twine behind the loops on the neck of the bag with its free end clear of the loops and the cutter 47 moved forward and closed on the feeding end of the twine to sever it a short distance from the twine carrier 10. The needle 111 after tying or knotting the. twine continues to move down until its upper end passes below a latch opening device. as a small brush 1. 123 attached to the bed oi the machine and so arranged as to act on the latch and move it away from the book of the needle as the needle is again raised to be in operatiur pd sition; see Fig. 5. The needle. 111 is car ried by a lover or swinging arm 134, being by a suitable means, as-a nut, secured to its end. This lever is tilted to rock on a stud 135 extending lmrizontaltv from a bracket secured to the bed of the i'miehine, and from the hub of this lever projects upwardly a short arm 136, which by an adjustable rod 137 is connected to a lever 138, rocking on the stud 27 and provided with a roller 125$) working in the groove of the cam'b secured to the. main shaft (1.

The pusher 132 is formed on or attached to the end of a bar 140, which is fitted to slide in a bracket piece 141 secured to the bed of the. machine. A lever 142 pivoted at 14 1 to the upper end of the bracket piece 141 connects to the sliding pusher bar 140 by a slot at its lower end embracing a pin 1'14 projecting from said bar, and the upper end of this lever 142 is by a link 145 connected to a curved extension of the lever 18, which carries the gripping device, or to an arm H secured to said lever 18. This RI"- rangemcnt of parts provides a simple and elieclive means for actuating the pusher 132, as it operates ,in conjunction with the twine gripper when it lifts the leading end of the twine, to push the twine against the needle when in position to be engaged by the hook of the needle.
